## Our take

What our shortlists say about the one we picked.

### [CyCognito EASM Platform](https://cybersectools.com/tools/cycognito-easm-platform)

Best for: Teams wanting discovery plus active testing

It earns a place because discovery and active testing come in one product, so findings arrive already checked and not as a raw asset list. That suits mid-market and enterprise teams that want proof before they assign work. Testing live assets needs their owners on board, so settle scan cadence and scope before you turn it on.
